Specifications

Description

These NHS-ester compounds react to form covalent bonds with primary amines (e.g., side chain of lysine residues or aminosilane-coated surfaces). The phosphine groups (PPh2) react with azide-labeled molecules by a mechanism known as Staudinger chemistry, enabling efficient and specific conjugation of derivatized molecules in biological samples. In combination with different azide-tagged compounds, these NHS-Phosphine reagents facilitate a variety of labeling and crosslinking experimental strategies for investigating protein interactions and cellular pathways.

Highlights:

  • Versatile – Sulfo-NHS-Phosphine easily dissolves in water-miscible solvents for subsequent dilution in aqueous reaction mixtures for azide conjugation; NHS-Phosphine can be used for amine surface modification in organic solvents

  • Compatible – reaction chemistry occurs effectively in simple buffer conditions; requires no accessory reagents such as copper or reducing agents

  • Specific – NHS esters are specific for covalent attachment to primary amines (side chain of lysine or N-terminus of polypeptides)

  • Chemoselective – azide and phosphine groups do not react or interfere with components of biological samples but conjugate to one another with high efficiency
